By the construction of the bolt and its operatingcam plate, binding of the dog is prevented.

The dial plate 24: is secured to the outer side of the door25 and screws or rivets attach both the dial plate and the lock casing toa door, in the present instance.

On the dial plate is a barrel 26, which is I a retaining ring 32, which secures the knob to the dial plate The knob has a hole 33 to receive the spindle 19. a projection 34, which enters a groove in the knob, thereby insuring the. turning of the spindle and the lock mechanism with the adjustment respect to the lock casing to accommodate knob. The construction also allows for ofthe dial plate and the knob in doors of different thicknesses.

' I claim: 1
